Data for the study of Posidonia microbial nitrogen metabolism manuscript
These are data related to the study of the seagrass microbiome and function. Posidonia oceanica , an endemic seagrass species that dominates the Mediterranean Sea, achieves high abundances in seawater with relatively low concentrations of dissolved inorganic nitrogen. Here we test whether microbial...

These are data related to the study of the seagrass microbiome and function. Posidonia oceanica , an endemic seagrass species that dominates the Mediterranean Sea, achieves high abundances in seawater with relatively low concentrations of dissolved inorganic nitrogen.
